9. MAINTENANCE PROCEDURE

Position the machine in such a way that it can be checked easily.
Wear the correct individual protection gear in order to avoid contact with the mineral oil.
It is necessary to periodically check as follows:
VERIFICATION
The state of lubrication
The oil/grease level
Cleanliness of the filling and intake filter (where fitted)
The machine does not require special equipment for any inspection and/or maintenance activity. It is however
recommended that the equipment used be suitable and in good condition so as to avoid damage to people or parts of
the machine.
9.1 Assembly/Disassembly
No pump assembly operations are envisaged.
For wall mounting ensure adequate space is available (as shown in the installation diagram) to avoid abnormal
postures and possible impacts; four fixing holes are provided for wall mounting and three for base fitting.
Subsequently it will be necessary, as previously described, to connect the pump to the machine hydraulically and then
to connect the control panel.
During the disassembly phase ensure the tank is empty.
Disconnect the electrical and hydraulic parts.
Where the machine is to be scrapped, do not dispose of potentially polluting parts in the environment, following local
regulations for their correct disposal.
At the time of the machine being scrapped it is necessary to remove and destroy the identification plate and all other
relative documents.
9.2 Regulation
Flow rate (for versions with adjustable flow rates)
It is possible to regulate the flow rate by rotating the regulating screw (8 mm hexagonal key) clockwise to decrease
and anticlockwise to increase (remove the cap B).
9.3 Repairs
The following diagnostic table indicates the main anomalies which may be encountered, the probable causes and
possible solutions.
The anomalies shown are:
• the pump fails to deliver lubricant
• irregular pressure
• irregular flow rate
In case of doubts and/or problems which cannot be resolved do not attempt to disassemble parts of the machine but
contact the Engineering Department of DROPSA S.p.A.
